Nextcloud AIO "Connection closed" error in client

Hi, I’m using the Windows client to connect to an AIO instance of nextcloud, and am getting “Connection closed” errors in the client when syncing large files (not sure of the exact threshold but it seems to happen with files larger than 50Mb).
This is the command i’m using to start the server:

sudo docker run \
--init \
--sig-proxy=false \
--name nextcloud-aio-mastercontainer \
--restart always \
--publish 80:80 \
--publish 8080:8080 \
--publish 8443:8443 \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \
--env NEXTCLOUD_MOUNT="/mnt/" \
--env NEXTCLOUD_DATADIR="/mnt/ncdata" \
--env NEXTCLOUD_MEMORY_LIMIT=2048M \
--env NEXTCLOUD_UPLOAD_LIMIT=200G \
--env SKIP_DOMAIN_VALIDATION=true \
nextcloud/all-in-one:latest

And I verified in the Nextcloud system settings interface that the PHP max memory is 2G as it should be.
I’ve also added maxChunkSize=500000000 to the nextcluod.cfg of the client since that seems to be a common solution but it hasen’t fixed the issue for me.
Thanks in advance!

I might be wrong, but I’m pretty sure it’s the latest update to the desktop client (3.14.0) which is responsible for breaking this. Do give an older version a try and report back your findings. You can get the installers here
